Directx11 tutorial 39 texture ing (9)

In mytutoriald3d11_32, we add a texture textureclass * m_texture in planemodelclass; to read a grass texture. After the program is executed, the effect is as follows:

In mytutoriald3d11_33, we removed the texture resource view member variable in the model class, and also removed the textureclass class. In this case, we used a texture management class texmanagerclass to manage all the texture resources, texture management is more convenient. Previously, texture resources are placed in each model class, so that each model can correspond to only one texture, which is inconvenient.

The texture management class is very simple. It uses a vector to store all the texture resource views. STD: vector <id3d11shaderresourceview *> m_texturervs; the resource management class stores the Resource Name and resource itself, the createtex function is used to return the texture resource. If the texture resource does not exist, the texture resource is created.

Id3d11shaderresourceview * texmanagerclass: createtex (id3d11device * device, string filename)
{

// If the texture resource already exists, return; otherwise, create
For (INT I = 0; I <m_texturervs.size (); ++ I)
If (! M_texturenames [I]. Compare (filename ))
Return m_texturervs [I];

Hresult result;
D3dx11_image_load_info loadinfo;
Zeromemory (& loadinfo, sizeof (d3dx11_image_load_info ));
Loadinfo. bindflags = d3d11_bind_shader_resource;
Loadinfo. format = dxgi_format_bc3_unorm;
Loadinfo. miplevels = d3dx11_default; // The maximum mipmaps layer is generated.
Loadinfo. mipfilter = d3dx11_filter_linear;

Id3d11shaderresourceview * Rv = 0;

// Create a texture resource view from a file.
Result = d3dx11createshaderresourceviewfromfile (device, stringtolpcwstr (filename), & loadinfo, null, & RV, null );
If (failed (result ))
{
HR (result );
Return false;
}

M_texturenames.push_back (filename );
M_texturervs.push_back (RV );

Return RV;
}

In graphicsclass, we define the member variable texmanagerclass * m_texmanager. In the rendering function, the last parameter uses m_texmanager-> createtex (m_d3d-> getdevice (), string ("grass. (DDS.

// Put plane vertices and index data into the buffer for rendering
M_planemodel-> render (m_d3d-> getdevicecontext ());
// Use light shader texture for rendering

Result = m_lighttexshader-> render (m_d3d-> getdevicecontext (), m_planemodel-> getindexcount (), worldmatrix, viewmatrix, projectionmatrix,
Light, material, camera, m_texmanager-> createtex (m_d3d-> getdevice (), string ("grass. Dds ")));
If (! Result)
{
Return false;
}

// Perform the translation operation to obtain the final model world matrix.
D3dxmatrixrotationx (& worldmatrix1,-1.57); // PAI/2
D3dxmatrixtranslation (& worldmatrix2, 0.0, 0.0, 8.0 );
D3dxmatrixmultiply (& worldmatrix3, & worldmatrix1, & worldmatrix2 );
Result = m_lighttexshader-> render (m_d3d-> getdevicecontext (), m_planemodel-> getindexcount (), worldmatrix3, viewmatrix, projectionmatrix,
Light, material, camera, m_texmanager-> createtex (m_d3d-> getdevice (), string ("stone01.dds ")));
If (! Result)
{
Return false;
}

After the program is executed, the interface is as follows. Because the two planes use the same model and the diffuse reflection coefficient is the same, the front wall is also green.

In mytutoriald3d11_34, we changed the PS code and directly used the texture as the Kd, which is much better.
